Question

When I am 5% older than I am now, I will be 21 years old. How old am I now? Give me a explanation too.

Answer 1

Answer:20years.

Step-by-step explanation:

Let your present age be 'x'

If you are 5percent holder then your age is 21

x +5/100×x =21

x+5x/100=21

100x+5x/100=21

105x/100=21

x=21×100÷105

x=20
